# height(at:)

Retrieves the height of an individual pin on the braille display.

```
func height(at point: CGPoint) -> Float
```

## Parameters

`point`

The location of the pin to retrieve the height for. The bottom-left of the display
is at `{ 0,0 }`, and the top-right of the display is at `{ dimensions.width - 1, dimensions.height - 1}`.

## Return Value

A floating-point number between `0.0` and `1.0` that specifies the height of the
pin. A value of `0.0` indicates that the pin is completely lowered, and a value of
`1.0` indicates that the pin is completely raised.
